Hi! I'm dealing with this problem that seems to be very easy, however the teacher says I'm wrong, and I don't know where's my mistake (She didn't tell me). So I hope you can tell me where did I go wrong Here's the problem:
A falling sky diver travels 64m in 2 seconds. How much will he travel in 8 seconds? (Ignore the air resistance)
I used the equation y=yo+vot+1/2gt^2
Then I solved it for vo, obtaining vo=22.2 m/s. And finally obtained:
I don't know what did I do wrong, and the teacher didn't even tell me what was the right answer. I hope you guys help me figure it out. Thanks!
